To all whom it may concern: 3 I

Be it known that 1,.ROBERT B. SMITH, a citizen of the United States, and a resident of Brooklyn, inthe county of Kings. and State of New York, have invented certain new and useful Improvements in. Corner Fastenings for Bedsteadaof which thefollowing a specification.

The invention relates beds and more particularly to improvements in what are commonly designated as three-: piece beds, these comprising a head-frame, a foot-frame and a mattress or spring carrying frame intended for detachable connection with the head and foot frames. My invention has reference more particularly to the corner-fastenings by which the mattress or spring carrying frame may be conveniently and rigidly secured to the head'and foot frames, and resides more especially in novel corner-fastening members secured to the side-rails of the spring or mattress carrying frame and which usually receive the endrails of said frame, and novel locking members connected with the corner'posts of the bedstead and adapted to receive and interlock with said corner fastening members of the spring or mattress frame, the whole being so arranged, combinedandconstructed that a very substantial bedstead frame may be produced.

The invention resides in the novel features and construction of interengaging parts hereinafter described, and particularly pointed out in the claims, and said inven-. tion will be fully understood from thede tailed description hereinafter presented, reference being had to the accompanying drawin s, in which: I

Fig. 1 is a side elevation, partly broken away, of one corner-portion of a bedstead equipped with the cornerefastening of my invention; I

Fig. 2 is a top View, partly in section and partly broken away, of thesame; A 1

Fig. 3 is a horizontal-section through the same, taken on the dotted line 3- 3 of ig. 1;

Fig. 4 is an outer end elevation of the corner-fastening membersecuredfto the side rail of the spring or mattress carrying frame, and i 1 Fig. 5 is a side elevation of a corner portion of a bedstead employing my invention in a form'varyi-ng from the. embodiment thereof shown inFigs; 1 to 1 inclusive and s therefor constituting fa modified. construe;

to improvements in 1 tion, which,.however, may in some instances beregarded as the preferred form of the inventionp.

In"the.dra'wings,:10 designates a portion of a corner-post of a metal bedstead, 11a portion of one ofthe side rails thereof, 12 a portion .of .one of-the angle-iron end rails, 13 the usual helicals connected with said end-rail,and11etaportion ofthe mattress or spring supported endrail12'. 1

My invention has reference more particularly to means, commonly called a corner fastening, for connecting thev side-rails 11 and end-rails 12 with? the corner-posts of the bedstead. 1,

Referring to Figs. -1 to .4: inclusive, one member of the corner-fastening is numbered 15 and the other member thereof 16, the member 15 being secured to the side rail 11 andthe-member'16 to. the corner-post 10. The members 15, 16 are, preferably, each an integral metal casting. I

The fastening member 15 has a vertical outer endqface-plate-l'Y, a top flange 18, a lower .partly tubular portion 19 to engage and be secured to the side-rail, an inner vertical strengthening web 20, and anoutwardly projecting vertical web 21,v which is in horizontal alignment with the web 20 and projects towardthe corner post 10.

bysaid helicals from the The tubular portion 19 of the member 15 v forms a socket for the end of the side-rai1 llfand may be secured thereto by a rivet 22. The upper portion ofthe face-plate 17 and the flange 18,may conveniently have the endrail 12 secured thereto by means of rivets 23.

The essential feature of the member 15 pertains tothe web2l, which is a locking bar and has on its opposite sides substantially vertical'integral corresponding ribs 24: and i on its upper and lower outer end edges abut ment projections 25,- 26, whose operative faces are vertical and preferably on the same vertical plane. The web or bar 21 is recessed inwardly between the projections 25, 26 and J to the outer vertical edge of the ribs 24:, as shown in Figs. 1 and 4:. The ribs 24 present at their inner vertical edges substantially flat corresponding downwardly and outwardly inclined wedge-faces 27, at whose lower ends the ribs 2 1 curve outwardly, as at 28, t0 facilitate the application of the fastening member 15 to the fastening member 16. The locking bar or web 21 thus provideson its opposite sides the corresponding '0 wedges 27 and on its outer end the upper and lower abutments 25, 26, these abutments being for cooperation with the fastening member 16, as hereinafter explained. j

The fastening member 16 is preferably in one integral piece and may be conveniently secured to the corner-post 10' by rivets 29, and said member 16 has at its upper and lower end portions, upper and lower abutment faces 30, 31, respectively, and at its opposite sides, corresponding arms 32, which project horizontally toward the member 15 and have on the facing sidesof their outer ends corresponding lugs 33 presenting curved inner edges, as indicated by dotted lines in Fig. 1, to the .flat wedge faces '27 of the ribs 2%. vThe abutmentfaces 30, 31 are preferably vertical and in line with each other and they cooperate with the upper and lower abutment faces 25, 26 of the fastening member 15.

In applying the member 15 to the member 16, the said parts are-brought together and the outer portion of the locking bar 21 of the member 15 is caused to pass downwardly between the arms 32 of the'member 16 with its wedge surfaces '27 against the curved surfaces of the lugs 33 until the abustmcnts 25, 26 on said bar "21 enter into firm engagement with the abutments 30, 31 0f the member 16 and become bound thereto by the wedging action of the surfaces '27 said lugs 33.

The ribs 24c strengthen the bar 21 and the wedges 27 afforded by said ribs have subtantiallyonly a point contact with the lugs 33 :and therefore are effective in binding the fastening members 15, toitogether, By .rea-' son of the provision of two corresponding wedges 27 to engage lugs .disposedat opposite sides of :the bar 21, the members 15, 16 become very efiiciently secured together without liability of one member being in tiltable or rockable relation to the "other member. The abutting faces 25, 26 and 30., 31 are of adequate but limited surface area and hence may be conveniently machined or smoothed, if desired, at small expense. The fastening members 15., 16 have, as a whole, been designed with the view of rendering them highly eliicient, ready of manufacture and assembly and of great durability.

The face-plate 17 on the member '15 preferably extends laterally beyond both sides of the web or bar 21 and web 20, so as to adapt the member 15 for any post of the bedstead, thus avoiding the necessity of providing right and left hand members 15 for the -op posite-corner posts of a bedstead. The faceplate 17, may, however, extend lateral-"1y beyond only one side .of the web .20 and bar 21 should it appear not to be objectionable to make the members 15 .as rights ;and".=le-f.ts.

in the construction shown in Fig. 55., 10 desiguiates the corner-posts,-&t1 :a side rail of against the mattress or fabric carrying frame, 42 the cornerr'fastening member secured there to and a3 the corner-fastening member secured to the post 40. The member 43 has abutment projections 44, 45, side arms 46 and rounded lugs e7 corresponding with the like features numbered 30, 31, 32 and 33 respectivelyin Figs. 1, 2 and 3 and requiring therefore no special description except to point out that the arms 46 are lower on the member '43 than the arms .32 on the member 1.6. The member .42 has a socket 48 to receive the end of the side rail 41 and a body or vertical bar portion .49 on whose upper and lower ends are formed abutment projections 50,61 respectively and on whose opposite side faces are formed substantially vertical ribs :52 which are oppositely inclined on the innered-ges of their upper and lower portions'to afford upper and lower wedges 53, 54 for respective engagement .with the curved surfaces of the lugs .47. The abutment projections .50, 51 correspond with the like features numbered 25, 26 in Figs. 1, 2 and a and they. "cooperate with the abutment pnojeotions 44, 45 on the member 43 in a manner which will be understood from the description :hereinbefore given with respect to the abutments 25., 26, and 30, 31. It is intended that the member 42 may be applied to any corner of the mattress-frame and that no care need be taken as to which end-of said member may be at the top and hence each horizontal half of said member 42 is .a duplicate of the other half thereof, one half haying the wedges '53 and the other half the wedges 64 and either pair of wedges being adapted to be passed downwardly be tween the arms. 46 to engage the lugs 47. The member 42 of the construction described presents some advantages in lessening the care which ordinarily would be required in assembling the parts of a sbedstead but said member when in position performs the same duties :as the aforesaid member 15 and in the same way. it is my invention to apply my corner-fastening members 15, 42 to box-- spring mattresses, as well as to 'the frames of spring fabric mattresses, and the members 42 will :be found to the very convenient of application to corner portions of box-spring mattresses having suitable frames :to receive them.

-What I claim as my invention and desire to secure by Letters-Patent, is: I
